Definitions

  • This invention relates to an insertion device which is capable of guiding expansion of an expandable structure towards or away from a desired direction and/or interior region of an animal or human body.
  • This invention further relates to an insertion device for inserting expandable structures, such as medical balloons, into an interior region of a human or animal body, wherein the device is capable of expanding at the tip. Also described are methods of using the disclosed devices in the repair, augmentation and/or treatment of fractured and/or diseased bone.
  • Expendable structures such as balloon dissectors and catheters, are used in various surgical procedures and for various rehabilitative purposes in the medical arts.
  • balloon catheters are commonly inserted into veins and arteries to expand blood vessels, most commonly to dilate and/or remove obstructions in the blood vessel (e.g. to remove constrictions blocking blood vessels which can cause a heart attack or stroke).
  • Other types of surgical balloons have been used to aid surgeons in accessing specific organs during surgery, usually in lieu of previous insufflation techniques.
  • Such balloons are commonly inserted in a deflated state through an insertion device comprising a cannula, catheter tube, or other similar device, and are positioned under an organ.
  • the balloon may then be inflated to lift and separate a desired organ away from surrounding organs and tissue to make sides of the desired organ easier to access during surgery.
  • the balloon may also be placed and inflated so as to lift and separate other organs and tissues, leaving the desired organ for surgery exposed beneath.
  • Medical balloons have also been used during procedures for repairing and/or reinforcing fractured and/or diseased bones. Some physicians have used such balloons to create a working space adjacent fractured and/or diseased bone to allow the installation of plates, screws and/or other implantable articles to the bone.
  • a cannula is generally inserted through an incision in the skin near the fracture area.
  • a balloon is then inserted through the cannula and inflated between the bone and surrounding tissue around the fracture site to create a working space.
  • a support plate and bone screws, or other similar implements, can then be installed at the fracture site through small incisions in the skin. This type of procedure allows a surgeon to install implantable articles without having to make a long skin incision to isolate and expose the bone.
  • balloons have been employed inside fractured and/or diseased bones to repair, reinforce and/or treat the bone.
  • balloons can be inserted through a cannula and inflated inside the bone, which can compact cancellous bone, create a cavity and move cortical bone.
  • the cavity can be filled with a suitable bone filler, such as bone cement (e.g., polymethylmethacrylate - PMMA), autograft or allograft tissue, or various other bone substitutes.
  • bone cement e.g., polymethylmethacrylate - PMMA
  • autograft or allograft tissue e.g., autograft or allograft tissue
  • various other bone substitutes e.g., bone cement, autograft or allograft tissue, or various other bone substitutes.
  • US-5,601,590 discloses an expandable cannula for surgical use which when expanded creates a full-size instrument passage.
  • US-5,176,683 discloses an expandable prosthesis press for holding a prosthesis in place against bone while a cement placed between the prosthesis and the bone cures.
  • US-5,116,305 discloses an expandable balloon for use in the aorta.
  • the balloon is attached to one end of an inflation catheter and is equipped with a supporting member which extends from the catheter into the balloon interior.
  • US-5,961,499 discloses an expandable cannula for surgical use which when expanded creates a full-size instrument passage.
  • US-5,865,728 discloses a method for separating tissues using an inflatable balloon.
  • WO 98/56301 discloses systems for treating fractured or diseased bones using expandable bodies. According to some embodiments, multiple expandables bodies are deployed in the bones.
  • the present invention provides insertion devices which may be used with an expandable structure such as a balloon catheter to direct the expansion of the structure toward or away from a desired direction.
  • Directed expansion of the expandable structure provides the physician with significant control over the compression of cancellous bone and creation of cavities within the bone, as well as control over the movement of cortical bone.
  • the controlled expansion of an expandable structure allows the physician to tailor the shape and dimensions of the cavity, and the resulting shape and dimensions of the bolus of filler material contained therein.
  • directed expansion of an expandable structure permits a physician to minimize disruption of healthy cancellous and/or cortical bone during a treatment procedure, thereby further enhancing healing of the bone after treatment. Accordingly, the devices and methods disclosed herein permit the physician to optimize the ability of the bone to withstand compressive forces and/or heal as quickly as possible after the procedure is completed.
  • Expandable structures such as balloon catheters and dissectors are typically formed in spherical or elliptical shapes, and normally expand substantially outward. These balloons are desirably fairly low-profile such that they can fit through a cannula. Once inserted through the cannula into the region of treatment, such balloons will generally inflate fairly symmetrically about the axis of the cannula or other insertion device. However, as discussed in U.S. Pat. No. 5,972,015 , inflation of a balloon about the cannula's axis can be undesirable in some situations. To account for these situations, various alternative balloon designs and expansion constraint arrangements have been proposed, such as those described in the 015 patent.
  • the inventions disclosed herein further permit a practitioner to utilize a wide variety of expandable structures in conjunction with the methods and devices disclosed herein. Because the cannula or other insertion device substantially guides the direction of expansion of the expandable structure, there is less need to incorporate expansion constraints in the expandable structure itself. In addition, if the insertion device is comprised of a radiopaque material, the orientation of the device itself can be visualized during the surgical procedure under x-ray fluoroscopy, allowing the practitioner to visually verify the direction of expansion of the structure throughout the entire procedure. Of course, it should be understood that the devices and methods of the present invention could also be used in conjunction with expandable structures incorporating various expansion restraint arrangements.
  • an insertion device comprises a hollow member, which is preferably cylindrical, with a distal end and a proximal end, wherein the distal end is the tip, or point of insertion, of the insertion device.
  • the distal end of the hollow member desirably comprises a platform which constrains expansion of the expandable structure in one or more directions, but permits the expandable structure to expand in non-constrained directions.
  • the platform of the hollow member acts as a support or foundation against which the expandable structure pushes as it expands.
  • the supporting action of the platform induces the expandable structure to expand away from the platform, allowing the practitioner to direct expansion towards and/or away from a desired region.
  • the platform comprises a platform or expansion guide which is inserted through a hollow member of an insertion device, the guide desirably extending distally past the tip of the hollow member and into a bone.
  • the guide will desirably act as a support or foundation against which the expandable structure expands, inducing the structure to expand away from the guide. Because this embodiment of the guide travels through the hollow member, and need not initially penetrate soft tissues and/or the harder cortical bone, the guide design can be optimized to provide maximum support for the expandable structure.
  • an insertion device comprises a hollow member with a distal end and a proximal end, wherein the distal end is the tip, or point of insertion, of the insertion device.
  • the distal end of the hollow member desirably comprises a platform which directs the expansion of the expandable structure in one or more directions.
  • the distal end of the hollow member further comprises one or more crease or fold lines along which at least a portion of the platform desirably deforms after insertion into a bone. By deforming along predetermined lines, sharp surfaces on the platform are desirably moved away from the expandable structure.
  • bending of the platform can significantly affect the surface area of the platform in contact with the expandable structure as well as the strength and resistance to deformation of the platform.
  • the platform can be withdrawn through the cannula, with the distal end of the insertion device desirably bending the platform towards a lower-profile shape for removal.
  • the insertion device comprises a hollow member having a plurality of score lines spaced about the circumference of the distal tip, these score lines desirably forming a plurality of adjacent sections oriented in a first, lower profile orientation.
  • the adjacent sections can be expanded outward to a second orientation, where the adjacent sections substantially form a funnel, cone or flare at the tip of the insertion device.
  • the flared tip desirably guides the expandable structures into the cannula, facilitating passage of the expandable structure into and through the cannula.
  • the adjacent sections can further incorporate one or more guides or ribs which desirably impinge upon the expandable structure, folding and/or twisting the expandable structure along desired lines and/or in a desired manner, further facilitating removal of the expandable structure through the cannula.
  • the withdrawal of the insertion device through the harder cortical bone desirably bends the adjacent sections back towards and/or into their first, lower profile orientation.
  • an insertion device constructed in accordance with the teachings of the present invention is inserted through cortical bone and into cancellous bone in a vertebral body of a patient.
  • the insertion device is positioned such that the platform directs the expansion of an expandable structure towards a section of cortical bone to be moved to a desired position, such as a depressed upper or lower plate of a vertebral body.
  • the expandable structure is expanded against the platform, which desirably induces the expandable structure to expand substantially away from the platform, compressing cancellous bone to form a cavity and moving the targeted section of cortical body towards a desired position.
  • the expandable structure is contracted, and the cavity is then filled with an appropriate bone filler material.
  • This method which permits manipulation of cortical bone with a minimum of cancellous bone compression, allows a practitioner to move targeted cortical bone while preserving much of the cancellous bone in an uncompressed state. In addition, this method permits the practitioner to maximize the force which the expandable structure exerts on the cortical bone.
  • an insertion device constructed in accordance with the teachings of the present invention is inserted into cancellous bone in a vertebral body of a patient.
  • the insertion device is positioned such that the platform directs the expansion of an expandable structure towards a section of cancellous bone to be compressed.
  • the expandable structure is expanded, which desirably compresses some or all of the targeted cancellous bone, creating a cavity within the cancellous bone.
  • the expandable structure is contracted and, if desired, the insertion device is repositioned such that the platform directs the expansion of an expandable structure towards another section of cancellous bone to be compressed.
  • the expandable structure is expanded, compressing some or all of the targeted cancellous bone and increasing the size and/or altering the shape of the cavity within the bone. If desired, the procedure can be repeated to create a cavity of desired dimensions. The cavity is then filled with an appropriate bone filler material.
  • This method which facilitates the creation of large cavities within the bone, allows the practitioner to tailor the cavity shape/size to optimize the post-treatment strength and/or healing of the bone.
  • the disclosed method can be used to reposition cortical bone towards a desired position, permitting a practitioner to gradually displace small or large sections of the cortical bone, at the practitioner's option.
  • the disclosed devices and methods facilitate a practitioner's ability to repair, reinforce and/or treat targeted bone regions in situations where the insertion device is initially positioned near a cortical bone wall of a targeted bone region. Because the disclosed devices and methods provide substantial control over the direction of expansion of the expandable structure, the practitioner can position and/or reposition the platform to shield the nearby cortical bone from some or all of the expandable structure during some or all of the surgical procedure. Depending upon the orientation of the platform, the structure can be expanded to differing dimensions, desirably maximizing compression of cancellous bone and/or movement of cortical bone at each orientation. Accordingly, there is no need to reorient the entire insertion device to accomplish the objectives of the procedure, which desirably eliminates a source of additional trauma occurring during the procedure.
  • an insertion device is inserted through cortical bone and into cancellous bone in a vertebral body of a patient.
  • a stylet in the insertion device is removed, causing the distal end of the hollow member of the insertion device to expand or flare.
  • An expandable structure is inserted through the insertion device into the vertebra, is expanded to create a cavity, and is contracted and removed through the insertion device.
  • the flared distal end of the insertion device desirably guides the structure into the insertion device.
  • the cavity is then filled with an appropriate bone filler.
  • the present invention overcomes the problems and disadvantages associated with current strategies and designs in insertion devices for use with expandable structures, such as medical balloons.
  • the present invention provides insertion devices which may be used with expandable structures to direct expansion of the structure as well as to assist in insertion and removal of expandable structures from an interior region of a human or animal body.
  • the methods and instruments suitable for such treatment are more fully described in U.S. Patent Nos. 4,969,888 , 5,108,404 , 5,827,289 , 5,972,035 , 6,048,346 and 6,066,154 .
  • Fig. 1 depicts a vertebra 41 to be treated using an expandable structure 310.
  • An insertion device 70 such as a cannula or spinal needle, extends through the cortical bone 69 of the vertebra 41, and into the cancellous bone 71.
  • An expandable structure 310 is introduced into the vertebra 41 through the insertion device 70, and desirably expands within the cancellous bone 71, typically expanding outward in a spherical, cylindrical or other manner thereby creating a cavity.
  • a practitioner will typically position the insertion device 70 a sufficient distance away from the cortical bone 69 to allow room for the structure 310 to expand outward.
  • the expansion of the structure and cavity creation may.be less than optimal.
  • Figs. 2 and 7 depict one embodiment of an insertion device constructed in accordance with the teachings of the present invention.
  • the insertion device comprises a hollow member 210 which may be any appropriate shape, but is preferably cylindrical.
  • the hollow member 210 has a distal end 250 and a proximal end 255, wherein the distal end 250 is the tip, or point of insertion, of the insertion device.
  • the hollow member 210 may be any appropriate length to allow the insertion device to provide percutaneous access to an interior region of a body requiring treatment. In one preferred embodiment, the hollow member 210 is approximately 12 cm long.
